I have a weird neighbor, so I installed cameras in my apartment. I'm not sure if I should tell her what I saw.

I have a weird neighbor. Every night, at exactly 3:33 AM, she runs up and down the stairs for 3 minutes and 33 seconds. I thought nothing of it the first night, but when I checked the clock and saw the pattern, I realized I won't be able to get back to sleep until she's finished. <br><br>I couldn't find out which apartment she lived in, but I knew it wouldn't be hard. I assumed that whatever caused her to run up and down the stairs at 3:33 AM was more important than getting a good night's sleep, so I knew she wouldn't quiet down if I talked to her about it. <br><br>To figure out if it was a problem worth escalating, I decided to set up cameras in the hallways. When I checked the footage the next night, I was shocked at what I saw. <br><br>There was no one running up and down the stairs.<br><br>I decided to keep the cameras running, thinking that maybe she had just stopped doing it for some reason. But she didn't. The next night, and the night after that, I heard the running and the cameras continued to show no one running the stairs. <br><br>As creepy as this was, it was technically possible that I was just dreaming I was hearing the footsteps. It hadn't been a big problem before I saw the footage, and I was a bit of a heavy sleeper. <br><br>I decided to keep the cameras running to see if they would pick up anything else. The next night, I set an alarm for 3:33 AM and got out of bed to watch. <br><br>I heard the running, but the cameras didn't show anything. Something was going on. Thankfully, I was now sure I wasn't dreaming.<br><br>I decided to go into the hallway, but I was going to do it in a way that I wouldn't be seen. <br><br>The cameras had been enough to figure out which floor she lived on. And I knew there were windows in one of the stairwells that overlooked the parking lot. We lived on the 3rd floor. So I went down to the 1st floor. <br><br>I stood at the window, looking outside, pretending to smoke a cigarette. And this is what I saw.<br><br>A figure. A young woman. With long hair. Running up and down the stairs. It was exactly as I had expected. <br><br>Then, I saw her face. <br><br>She looked right at me. <br><br>I froze. I had thought there was no way she could have known I was watching her, and I had made sure that my camera didn't pick up my face. <br><br>I remember telling a friend once, "If someone tells you not to do something, ignore them and do it anyway."<br><br>Not this time. <br><br>When she saw me at the window, she began running towards me. <br><br>I took off in a full sprint, not stopping or looking back until I reached my apartment. I shut and locked the door, and then ran to the cameras to see if she had followed me. <br><br>She had. <br><br>The footage showed her running to the door on my floor, but it didn't show her face. I had to know who it was.<br><br>When I saw her running towards the door, I had snuck up and opened it. A moment later, the front door opened and I saw her face. <br><br>It was my face.
